The Gravelord Sword inflicts Toxic buildup, making it one weapon of only two in the game to do so (the other being the Dark Silver Tracer).

The sword inflicts 30 points of Toxic per hit, and once the bar is filled, lasts for 10 minutes dealing 5 damage per second.

When compared to the other curved greatswords, the Gravelord Sword has the poorest scaling and physical damage per second. However, its versatile moveset (including Thrust-based attacks) and its Toxic effect compensate for this.

It can be obtained through the use of the "Catacombs Skip", allowing the player to have a massively strong weapon at the very start of the game if they can run through the Catacombs to grab the Eyes of Death and then enter the coffin.
